1188896 - Firefox crashes when skipping through HTML5 video

Status: RESOLVED WORKSFORME

(Core :: Audio/Video, defect)

Description

[JJ]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:38.0) Gecko/20100101 Firefox/38.0 Iceweasel/38.1.0
Build ID: 20150703062643

Steps to reproduce:

I started firefox with `firefox --safe-mode`, then opened a Youtube video and tried to forward into the video by clicking various locations on the "video timeline bar". After about 5-10 clicks, firefox crashes.


Actual results:

Here is the output from the terminal where Firefox was started:

jj@legend ~ % firefox --safe-mode

(process:4834): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
console.error: 
  [CustomizableUI]
  Custom widget with id loop-button does not return a valid node
console.error: 
  [CustomizableUI]
  Custom widget with id loop-button does not return a valid node

** (iceweasel:4834): CRITICAL **: gst_video_codec_frame_ref: assertion 'frame != NULL' failed
[1]    4834 segmentation fault (core dumped)  firefox --safe-mode
firefox --safe-mode  18.92s user 1.98s system 46% cpu 45.408 total

Please let me know if there is anything I can do to gather more information about this problem (where are the logs?).


Expected results:

Obviously firefox shouldn't segfault, especially not in safe mode. Note that this problem also occurs in regular mode.

Do you have a stacktrace?

Well, I do, but it's not very helpful:

Core was generated by `iceweasel --safe-mode'.

Let me see if I can get a better stacktrace with a build from mozilla.org. Will report back later.

What's the version of Gstreamer you're using to read HTML5 videos?

First of all, I downloaded firefox-39.0.tar.bz2 from the Mozilla website to see if I can reproduce the problem and get an informative stacktrace. I couldn't. No matter how much I skip over Youtube videos, the official Firefox build never crashes. Since I can't seem to reproduce my own bug anymore, this report should probably be closed.

Second, here is the output of `dpkg -l | grep gstreamer`:

Yes, as it works with the build compiled by Mozilla, I close it.
